Currently all architectures but microblaze unconditionally define
USE_ELF_CORE_DUMP. The microblaze omission seems like an error to me, so
let's kill this ifdef and make sure we are the same everywhere.Signed-off-by: Christoph Hellwig

Microblaze version 7.20.d is the first MB version which can be run
on MMU linux. Please do not used previous version because they contain
HW bug.
Based on WB support was necessary to redesign whole cache design.
Microblaze versions from 7.20.a don't need to disable IRQ and cache
before working with them that's why there are special structures for it.Signed-off-by: Michal Simek

We need to continue with next microblaze PVR version that's why
I have to remove that ancient version. These version strings not match

I believe that none use ancients versions. If yes they will be just
labeled as unknown version.Signed-off-by: Michal Simek

This was intended to allow manual override of CPU settings copied automatically
to Kconfig.auto, however it's problematic for several reasons, but mostly:* If the defconfig doesn't have ALLOW_EDIT_AUTO=y, then it's impossible for
that defconfig to iverride the values in the kernel source tree. This leads
to very strange errors where the kernel is compiled with the wrong CPUFLAGS.Next patch in the series will back out the default in Kconfig.auto to baseline
settings, so a kernel built with no default values will at least boot on any
hardware, just not make use of additional CPU features.Signed-off-by: John Williams

Two version are generated.
linux.bin.ub which is created from linux.bin file
and
simpleImage..ub which is created from stripped simpleImage. fileLoad address and entry point is for microblaze first instruction
which is CONFIG_KERNEL_BASE_ADDR variable.There is possible for simpleImage format parse _start symbol too.
simpleImage. is still stripped elf file
I cleared simpleImage..unstrip file because there are so big.
